A source told The Canadian Press on Thursday that DelBiaggio is back in talks with Predators owner Craig Leipold.
DelBiaggio is after a franchise for Kansas City. Balsillie was looking to bring the team to Hamilton.
The Canadian Research-in-Motion co-founder had reached a US$238-million deal to buy the Predators, but a binding agreement has yet to be finalized. DelBiaggio's original offer reportedly was a less lucrative US$190 million.
But Balsillie may have rubbed some of the NHL's movers and shakers by making no secret of his plan to move the Preds, even though there is a lease in place in Nashville - and the Nashville sale was not final.
DelBiaggo had said last week he was no longer involved in the chase for the Predators. But that has changed according to the source.
DelBiaggo is looking for a team to play in Kansas City's new Sprint Center.
